Reconnaissance surveys for this species Blooms May - October conducted during the blooming period for the Iron Salts project and Headworks project, were negative. Since then, that area has been exposed to routine disturbance by Facility operations. ESA’s Alternatives Constraints Analysis reconnaissance surveys for the Project for Congdon’s tarplant in August 2016 and the Project’s wetland delineation in August 2017 confirmed absence of the species.
